Anyone know what chipset is on the 2004 Chevrolet Express 3500 ECU. I want to delete the passlock on the vehicle, since I had to change out the wiring harness and since I couldn't find an original I had to go with a cheap chinese one. I don't think it'll end up working without the passlock being deleted though. It's cranking and it will turn on but immediately shut off.

28f400? i would believe

not what you asked for but fairly easy to wire in if your harness in not correct then 30 min reprogram as long as components are good

That would be a lot easier, thanks.
